Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If lead-acid batteries are used for power supply in aerial cable car systems, then electrical consumers can be powered during operation, but the batteries have short cycle life, require full charging intervals, are heavy, and need temperature protection
Solution Approach 1:
The patent changes the fundamental parameter of the energy storage medium from lead-acid batteries to a different battery chemistry (such as lithium-ion or nickel-metal hydride) that inherently provides longer cycle life, higher energy density, and broader operating temperature ranges, thereby resolving the contradiction between power supply capability and reliability
Solution Approach 2:
The patent replaces the mechanical/chemical system of lead-acid batteries with an alternative electrochemical system that eliminates the need for complex temperature protection mechanisms and full charging intervals, improving both reliability and ease of operation
2Use of energy by moving object
If lead-acid batteries are used for power supply, then electrical consumers can be powered, but the batteries are heavy making them unsuitable for cabin cable cars
Solution Approach 1:
The patent changes the energy storage medium to a battery type with significantly higher energy density (such as lithium-ion), which provides the same or greater power supply capability at a fraction of the weight, thereby resolving the contradiction between power supply and weight
Solution Approach 2:
The patent effectively counteracts the weight penalty by selecting a battery chemistry that provides superior specific energy, allowing the system to maintain power supply capability while dramatically reducing the moving weight that would otherwise hinder cable car performance
3Use of energy by moving object
If lead-acid batteries are used, then power can be stored for operation, but they require temperature protection against heat which involves great complexity
Solution Approach 1:
The patent changes to a battery chemistry that inherently tolerates higher operating temperatures and has a broader thermal operating range, eliminating or simplifying the need for active cooling systems, thermal sensors, and temperature management control circuits, thereby resolving the contradiction between energy storage and device complexity
4Use of energy by moving object
If lead-acid batteries are used, then power can be supplied during operation, but they cannot be loaded quickly and require several hours for full charging
Solution Approach 1:
The patent changes to a battery chemistry with superior charge acceptance characteristics and lower internal resistance, enabling rapid charging capabilities that reduce charging time from hours to minutes, thereby resolving the contradiction between power supply capability and charging time
Solution Approach 2:
The patent enables the battery to be pre-charged rapidly during brief intervals between operations, allowing the system to maintain continuous power supply capability without requiring lengthy charging cycles that would interrupt service
